Another object is to provide a' construction of the above nature 'characterized by features of strength and rigidity, capable'of dependable service with 13, as will be more fully described.
out need of repair. Another object is to provide such a construction neat and .attractive in appearance. Another object'is to rovide a construction of the above nature WlllCh is simple and wherein the parts are conveniently assembled or separated. Other objects will be in part obvious or in part 0 pointed out hereinafter.
Theqinvention accordingly consists in the features of construction, ,combinations of 1 elements, and arrangements of parts as will be exemplified in the structure to be hereinafter described and the scope of the application of which will be indicated in the following claims. v
In the accompanying drawing, in which are shown various possible embodiments of 3 this invention.
Fi -e 1 is a perspective of aportion of a pair of eyeglasses;
Figure 2 is a perspective of a connection between a temp e bar andrim, the parts being shown separated from one another;-
Figures 3, Land 5 are views similar to Figure 2, showing modified forms of the construction. Similar reference characters refer to simlar partsthroughout the several views of the drawing.
' Referring now to the drawing in detail,
there is shown in Figurel one side of a pair of eyeglasses or spectacles comprising a mm 10 containing a lens 11, a bridge 12, and
temple bar 13. The other half of the pair of eyeglasses is not shown in order to avoid unnecessarily encumbering the drawing, and.
it will be understood that the parts thereof are substantially indentical with-those shown. 'The eyeglass rim 10 which is of metal is split at its side adjacent the point where the temple bar 13 is joined thereto. Thetwo approaching end portionslO and 10 of the rim are provided with laterally projecting and abutting end pieces 14 and 15, respectively. These end pieces are firmly secured together, preferably by means of a screw 16 passing through the upper end piece 14: and threaded into'the lower end piece 15, whereby the two ends of the rim 10 are joined and the lens 11 secured in place within the rim. These two end pieces14 and 15 thus abutting and secured together form in effect a lug projecting laterally from the side of the eyeglass rim. Upon this lug is pivotally mounted the forward end of the temple bar Referring now to Figure 2, the parts just "described are shown in larger detail and with the temple bar moved away from its connection with'the rim. As clearly shownin'this figure, the endmembers 14 and 15 are preferably shaped to curve around rearwardl the forward end of the temple bar 13. For the sake of clearness, it may be here noted that by the term rearwardly is meant a direction rearwardly along the temple bar toward the ear-piece 13 forwardly being in the opposite direction, and that by the inner side of the temple bar or other parts is meant the side toward the face of the wearer, the
outer side being employed to denote the side remote from the face of the wearer. As is seen in Figure 2, the innerside portion of the lug formed by the abutting end members 14 and 15, at the end portion 17 thereof, is rounded and projects beyond the end 18 of the outer portion of the lug. The portion 17 forms a bearing for the temple bar 13 and is undercut or recessed in rounded form, as indicated at 19 at both its top and bottom surfaces.
The temple bar 13 is preferably of metal, and is shown as of rounded form at its rear portion and of a flattened form at its forward portion adjacent its connection with, the rim. At the forward end of the temple bar are formed a pair of spaced inwardly projecting parts 20 and 21 in the nature of flanges or cars. These ears arepreferably formed integrally with the metal of the temple bar, being stamped out therewith and bent over or struck up from the to some extent in a direction to meet I tour to mate with the rounded walls of the undercut'parts 19. These undercuts or recesses are of such a depth that the outer surfaces of the ears 20 and 21 are respectively substantially flush with the top surface of the end piece 14 and the bottom surface of the end piece 15. A pivot screw 23 passes through the part 20 and through the part 17, and is threaded into the part 21, pivotally connecting the temple bar with the eyeglass rim.
The temple bar 13 is thus pivotally mounted by means of the ears 20 and 21 embracing the rounded bearing part 17. As the temple bar is swung outwardly upon its pivot to normal position in use, the end 22 of the temple bar abuts the shoulder 18 of the end pieces 14 and 15 limiting the outward swinging of the temple bar. As is shown in Figure 1, the parts in this position closely mate so that no unsightly gaps are present.
Ihe construction described above is one which attains many practical and important advantages. The temple ybar embracing both of the end pieces 14 and 15 is provided with a firm, dependable joint therewith, and
there is no tendency to pry apart and separate the two end members. Itather, the two ears 20 and 21 of the temple bar tend to aid in holding the end members 14 and 15 snugly together, assisting the action of the screw 16. When the eyeglasses are in use, the joint is practically concealed, so that the construction presents an attractive appearance. By removing the pivot screw 23 and the screw 16, the parts may be separated andthe eyeglass rim spread for the removal or insertion of a lens.
Referring now to Figure 3, there is shown a slightly modified form. The construction disclosed in this fi re is substantially the same as that of Flgure 2, except that the bearing portion 17 embraced by the ears 20 and 21 of the temple bar is formed integrally with one only of the end members of the rim, for example, the end member 15. The curved surface 14 of the end member 14 mates with the forward surface 17 of the bearing member 17, and the screw 16 holds the two ends of" the rim together. With this construction, as with the construction shown in Figure 2, it will be seen that there is no tendency for the temple bar, due to its connection with the rim, to pry the two ends of the rim apart. Moreover, with the construction shown in Figure 3, the rim ends may be separated for insertion or removal of a lens, simply by removal of the screw 16 without in any way interfering with the connection of the temple bar. The parts are rigidly held together, the engagement of the curved surface 14 of the end piece 14 with the surface of the bearing 17 lending to the strength of the structure.
I In Figure 4 there is shown another form of connection. Inthis construction, one of the ends of the rim, such as the end 10", is
cessed or undercut, as at 19, to accommodate the flanges or ears of the temple bar. The end 10 of the eyeglass rim is provided with a projecting member 25 which is received in a recess 26 in the upper surface of the end piece 24. A screw 16 passing through the part 25 and threaded into the end piece 24 secures the ends of the rim together. In this construction, also, the eyeglass' rim and the temple bar are connected by a firm, dcpendable jointwhich is substantially concealed, and there is no tendency for the temple bar to pry apart the ends of the rim. Moreover, in this construction, as well as that of Figure 3, the eyeglass rim may be spread for the insertion or removal of the lens without interfering with the mounting of the temple bar.
The construction shown in Figure 5 is the same as that of Figure 4, except for the connecting means between therim end 10 and the lug 24. In this instance, the surface of the lug 24 is cut away as indicated at 27, and the rim end 10 is provided with a flange or end piece 28 adapted to be received in this cut portion 27 and rest therein substantially flush with the surface of the lug 24. To facilitate assembly of the parts, and to strengthen the structure, the piece 28 is preferably provided with a sloping end 28 mating witha sloping wall 27 of the cut portion 27. The screw 16 passing through the part 28 and threaded into the lug 24, holds the two ends of the rim together. In this construction, also, the rim may be spread without interfering with the mounting of the temple bar.
From the above, it will be seen that there are herein provided eyeglass constructions which embody the features of this invention and attain the objects thereof, including many important practical advantages.
s many possible embodiments may be made of the above invention and as many changes might bemade in the embodiment above set forth, it is to be understood that all matter ,hereinbefore set forth is to be interpreted as illustrative and not in a limiting sense.
I claim as my. invention:
